XRU-2475 ETFE2183 15% GLASS FIBER GREEN

The charts above compare 30% short glass-fiber filled samples and show a noticeable difference in the moisture uptake behavior of PK versus to PA6 & PA66. Compared to glass-filled PA6 & PA66, moisture does very little to affect the physical property change of glass-filled PK. 40% Glass-Filled Resin
